WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the
manufacturer at the address or telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service panel and lock service panel to
prevent power from being switched on accidentally. When the service disconnecting means
cannot be locked, securely fasten a prominent warning device, such as a tag, to the service
panel.
3. Installation work and electrical wiring must be done by a qualified person(s) in accordance with
all applicable codes and standards, including fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney)
of fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturer’s
guidelines and safety standards such as those published by the National Fire Protection
Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning
Engineers (ASHRAE), and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden
utilities.
6. Ducted fans must always be vented to the outdoors.
7. Do not use this unit with any separate solid-state speed control device.
8. To reduce the risk of fire, use only metal ductwork.
9. This unit must be grounded.
TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
A. Never leave surface units unattended at high settings. Over heat cause smoking and greasy
spillovers that may ignite. Heat oils slowly on low or medium settings.
B. Always turn hood ON when cooking at high heat or when flambéing food (i.e. Crepes
Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
C. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or
filter.
D. Use proper pan size. Always use cookware appropriate for the size of the surface element.
WARNING
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP GREASE
FIRE, OBSERVE THE FOLLOWING:*
1. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn off the burner.
BE CAREFUL TO PREVENT BURNS. If the flames do not go out immediately, EVACUATE AND
CALL THE FIRE DEPARTMENT.
2. NEVER PICK UP A FLAMING PAN - You may be burned.
3. DO NOT USE WATER, including wet dishcloths or towels - violent steam explosion will result.
4. Use an extinguisher ONLY if:
A. You know you have a Class ABC extinguisher and you already know how to operate it.
B. The fire is small and contained in the area where it started.
C. The fire department is being called.
D. You can fight the fire with your back to an exit.
* Based on “Kitchen Fire Safety Tips” published by NFPA.

air into spaces within walls or ceilings or into attics, crawl spaces, or garages.
2. Take care when using cleaning agents or detergents.
3. Avoid using food products that produce flames under the Range Hood.
4. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and
vapors.

construction dust, etc. off power unit.
6. Your hood motor has a thermal overload which will automatically shut off the motor if it becomes
overheated. The motor will restart when it cools down. If the motor continues to shut off and
restart, have the hood serviced.

MAINTENANCE
Proper maintenance of the Range Hood
will assure proper performance of the unit.
Filters
The filters must be cleaned approximately
once every 30 hours of operation (when
the central segment on the display goes
on or starts blinking).
Use a warm detergent solution. Grease
filters are dishwasher safe.
Remove filter by pushing filter towards the
back of hood and rotating filter downward.
Duct free(Carbon) Filters
The duct free filters should be changed every 6 months. Rotate the filters to remove and replace.
Hood Cleaning
Stainless steel is one of the easiest materials
to keep clean. Occasional care will help preserve its fine appearance.
Cleaning tips:
-Hot water with soap or detergent is all that is usually needed.
-Follow all cleaning by rinsing with clear water. Wipe dry with a clean, soft cloth to
avoid water marks.
-For discolorations or deposits that persist, use a non-scratching household cleanser
or stainless steel polishing powder with a little water and a soft cloth.
-For stubborn cases, use a plastic scouring pad or soft bristle brush together with
cleaner and water. Rub lightly in direction of polishing lines or "grain" of the stainless
finish. Avoid using too much pressure which may mar the surface.
-DO NOT allow deposits to remain for long periods of time.
-DO NOT use ordinary steel wool or steel brushes. Small bits of steel may adhere to
the surface causing rust.
-DO NOT allow salt solutions, disinfectants, bleaches, or cleaning compounds to
remain in contact with stainless steel for extended periods. Many of these com
pounds contain chemicals which may be harmful. Rinse with water after exposure
and wipe dry with a clean cloth.
Painted surfaces should be cleaned with warm water and mild detergent only.
